Decoded Word

So, I'm happy because of the upcoming game, the Minecraft Dungeons II. And in the Minecraft Launcher, there is a tab related to our new game with the giant ancient city statue and note blocks. If we press a note blocks with a specific pattern (first note block, third, seventh, sixth, fifth, second, fourth and eighth), then the portal will open and show the countdown. But if we press the note block five times, then the letter or number will appear in illageralt language. And if we repeat our pattern but pressing each note block five times, then after translating it to english we get this code: 1NF3C7ED. And 1 is similar to the "i", 3 is above the "e" and 7 is similar to "t", what created the word INFECTED. But... What is infected? Is Deep Dark an infection? (Add "II" after the topic)
